They might have the odd large one not enough to put on the site. But downsizing has been rampant with the supply, so there would be really few. I'd call them and ask.
We currently have only one of those 12.5mm gem quality freshwater pearls left, and it is white with a slieght rose overtone. I can always call up several of my contacts in HK and China and find a peach/pink one if necessary. MistofCassiopeia, PM me or email me if interested.
